Electronic Health Records

This chapter introduces and reviews electronic health record (EHR) systems as essential core health information technology (IT). It describes current and potential future EHR functionality and discusses some of the challenges and controversies for these systems. EHRs include both traditional and newer capabilities for direct patient care and population health, as well as innovative Health IT working in concert with EHRs. Today’s EHR landscape includes challenges around EHR data entry, increased patient participation in EHR data entry, certified EHRs with increased inter-operability, and a number of regulatory requirements often leveraging EHRs.

Notes

The terms “electronic health record” (EHR) and “electronic health record system” (EHRS or EHR system) are often used interchangeably, with no generally agreed upon distinction. The terms “electronic medical record” (EMR) and “electronic medical record system” (EMRS or EMR system) have also been used but many have moved towards using the term “health” versus “medical” as these systems are being used broadly across the continuum of care by a multitude of roles; again, the distinctions between EMR and EMRS are not generally agreed upon. The term “computer-based record system” has also been used in the past. In this chapter, and throughout the book, we will use the term “electronic health record”, with the acronyms “EHR” and “EHRs” to designate the singular and plural forms, respectively.
